Description
Zoom on the Ryobi RY905500
In a nutshell, the Ryobi RY905500 is a portable generator mostly geared towards:
- RV travellers who wish to upgrade their experience to another level
- People occasionally participating in outdoor fairs, festivals or events
- Food truck owners who do not wish to see their business interrupted under any circumstances
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Professionals in need of safely powering high-intensity work or lighting equipment
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.
Power & Run Time
The Ryobi RY905500
The Ryobi RY905500's design includes a gasoline-fueled 420 cc Ryobi OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 5500W and also a peak wattage of 6875W.
With a noise rating of 78 dBA (less noisy than a dishwasher), the generator features Ryobi's EasyStart pull-start mechanism (more information below).
Thanks to a fuel capacity of 6 gallons, the RY905500 can operate for around 10 hours at 50% load with a full tank (fuel consumption around 0.6 GPH).
The RY905500 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<20%).
Outlets
The control panel includes the following 5 AC outlets:
Because the RY905500 is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.
Portability
The Ryobi RY905500 has a conventional, open frame design, of the following dimensions: L31.5 x W29 x H24 in, which offers support and allows it to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 192 pounds. Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.
EasyStart Mechanism
Ryobi's 3-step EasyStart mechanism
The unit benefits from Ryobi’s EasyStart mechanism. This 3-step starting system allows you to easily start your generator. It works in the following way:
- Put the engine switch on the “ON” position, and place the lever on the “START” position
- Pull the recoil until the engine runs
- Let the engine run 15 to 30 seconds and place the lever on the “RUN” position
Features
The RY905500's control panel
To help you monitor the RY905500's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.
From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.
With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Ryobi RY905500 also comes with several accessories, including: tool kit and oil.
Emissions
The Ryobi RY905500 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor, making it usable in forested areas.
Product Video
The Ryobi RY905500 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Ryobi RY905500 compare to generators of similar power (between 5000 and 6000 W).
- A weight of 192 lbs makes the Ryobi RY905500 one of the heavier devices in the 5000-6000 rated wattage range. Regarding dry weight, one of the champions in the same power range is the Genmax GM6000XiE, with a dry weight of only 106.9 lbs.
- When compared to devices able to produce a similar running wattage, this generator and its lowest emitted noise of 78 dBA is on the noisier side. For those who are looking for a less noisy device, we suggest the Honda EU7000iS. With just 52 dBA, it is one of the most quiet devices in this power range.
- Regarding its autonomy, the autonomy of the RY905500, reaching around 10 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Cat RP5500, reaching around 15 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. This generator has an average fuel consumption among comparably powerful devices, as it reaches 0.6 GPH (gallon per hour) at a 50% load. If fuel consumption is your top priority, we suggest to check out the A-iPower SUA7000L, which has a fuel consumption of only 0.36 GPH and thus, is one of the most efficient devices in our database.
The bottom line
- Several accessories included
- GFCI Outlets
- Decent fuel efficiency
- No electric start
- Not CARB-compliant
- On the heavy side (192 lbs)
- On the noisy side (78 dBA)
- Relatively low run time
